Variance-Based Iterative Model Order Reduction of Equivalent Circuits for EMC Analysis

This paper proposes a novel and iterative way to conduct model order reduction (MOR) of linear equivalent circuit models (ECMs) without the use of a state-space representation as a surrogate model. The result is an ECM with a reduced total number of circuit elements but same system behavior. The pro...
